Differences in degradation conditions between pulp molded pl

Ununrestrained production and use of disposable plastic tableware will cause global energy problems.At present, the two methods to solve the use of disposable packaging plastic is to use paper tableware and biodegradable plastic tableware.

First of all, let's talk briefly about what is paper tableware and biodegradable plastic tableware?Paper tableware refers to pulp plastic tableware material (main material plant fiber).And degradable plastic tableware can be divided into three basic categories, photodegradation, biodegradable and starch degradation.

Let's talk about the degradation of pulp-molded tableware and biodegradable plastic tableware.

What are the conditions for biodegradable plastic tableware?

Producer statement: This process takes six months in industrial composting conditions.

What is the composting condition for industrialization?

Certain temperature: usually at 50-60 degrees Celsius, the general soil can not be reached.In addition, a certain humidity, a certain flora, and a certain oxygen consumption to achieve industrial composting conditions.These conditions are not achievable in any natural environment.

Regardless of the problem of materials itself, there is no universal industrial composting industry in China, and the garbage classification and recycling system is not working well.Promoting the use of "degradable plastic" will likely lead to new "white pollution".The propaganda of "degradable plastic" can easily mislead the public that it is a material that "can disappear by itself without handling".

What happens to get into ordinary soil?

In 2010, the Agricultural University of Athens, Greece used actual Mediterranean soil for PLA biodegradable plastic, and 11 months for only partial physical disintegration and partial fragmentation.In 2014, Central South University of Forestry and Technology simulated natural soil, and PLA made a plastic test in 12 months. Its quality loss was only 0.23% after 12 months, with almost no degradation.

What happens to get into the ocean?

In 2017, a 400-day trial at the University of Miloit in Germany put various biodegradable plastics degradable in industrial compost in sea water and fresh water, and the final PLA had only about 0.5% quality loss.Look at the biodegradable plastic tableware needs to degrade, so many harsh conditions.

Then let's look at the degradation conditions of the pulp plastic, just bury the pulp plastic tableware in the ordinary soil.

Since pulp molded tableware is made from pure natural plants and pulp fiber.(Grass pulp, wood pulp, bamboo pulp, reed pulp, etc.)

So it can degrade by 100%, with a far less impact on the environment than on biodegradable plastic tableware.

Advantages of pulp-molded flatware

1, environmental protection and hygiene, non-toxic and harmless;

2, can resist 120℃ hot oil and 100℃ hot water, without deformation and leakage;

3, is suitable for microwave baking, refrigerator frozen and fresh, cooking at high temperature;

4, has recycling value, waste can be recycled, save resources and protect the environment;

5, naturally degrades mudrification into organic fertilizer, reduced to carbon dioxide and water;

The 6, is generous in appearance, practical, low in cost, and easily accepted by consumers.
